As someone who is always on the go, I can confidently say that the Anker Portable Charger, specifically the 325 Power Bank (PowerCore Essential 20K), is a game changer for anyone who relies heavily on their devices. With a hefty 20,000mAh battery pack, this power bank is designed to keep my devices charged throughout the day without the constant worry of running out of battery. It provides an impressive capability of delivering more than 5 charges for an iPhone XS and almost 5 full charges for a Samsung Galaxy S10. For those who own an iPad mini 5, it offers over 2.5 charges, making it a versatile solution for multiple devices. This means I can easily take a weekend trip or have a busy day out without having to search for an outlet. The sheer capacity makes it an essential companion for anyone who leads a busy lifestyle.

One of the standout features of the Anker Portable Charger is its advanced charging technology. Anker’s exclusive PowerIQ and VoltageBoost technologies work together to deliver optimized charging speeds to my devices.

Additionally, the trickle-charging mode is a thoughtful touch, allowing me to charge low-power accessories without any hassle. It shows that Anker has considered the diverse range of devices we use in our daily lives.

The convenience of simultaneous charging is another feature I truly appreciate. With twin USB ports, I can charge two devices at once, which is perfect for when I’m on the move. I often find myself needing to charge my phone and my tablet simultaneously, and the ability to do so without compromising on charging speed is a huge plus. However, it’s worth noting that the USB-C port is designated for input only and cannot charge other devices, but this is a minor drawback considering the overall functionality of the power bank.

When it comes to recharging the PowerCore itself, I love the versatility offered by having both USB-C and Micro USB input ports. This means I can recharge it using various chargers I already own. Recharging with a 10W charger takes about 10.5 hours, which is manageable, especially if I can plug it in overnight.

This flexibility ensures that I can always keep the power bank ready for my next adventure.

What I find particularly reassuring is the comprehensive package that comes with the Anker Portable Charger. Alongside the power bank, I receive a Micro USB cable for charging the power bank, a welcome guide, and most importantly, an 18-month worry-free warranty. This shows Anker’s commitment to customer satisfaction, and their friendly customer service is an added bonus that gives me peace of mind.
